While the description of the utility model will be described in connection with the preferred embodiments, it is not intended to limit the inventive features to the implementation. Rather, the purpose of the utility model described in connection with the embodiments is to cover other alternatives or modifications, which may be extended by the claims based on the utility model. The following description contains many specific details for the purpose of providing a thorough understanding of the present utility model. The utility model may be practiced without these specific details. Furthermore, some specific details are omitted from the description in order to avoid obscuring the utility model.

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The inventors of the present utility model have desired to develop a plant concentrate paste production facility, which may be, for example, a loquat flower paste production facility. The common product in the market is loquat leaf extract, and the production of high-quality loquat flower extract needs to overcome a plurality of difficulties. The extraction of the effective components of the loquat flower is not easy, so that a lot of raw materials are wasted, and the yield is low. On the other hand, loquat flower is easy to break during extraction to generate smaller residues, is easy to remain in a final finished product, and is easy to cause pipeline blockage.

As shown in fig. 1, the present utility model provides a plant concentrating paste production apparatus comprising an extraction device 1 and a vacuum concentrating device 2. For example, the components in the plants are extracted, the plants and water are added into an extraction device 1 to form a mixed solution, the active components in the plants are extracted into the water by a heating mode to form an extracting solution, and the extracting solution is filtered to obtain pure extracting solution without plant fragments. The extracting solution flows into the vacuum concentration device 2 through a pipeline, and is concentrated into paste by adopting a vacuum concentration mode. For example, loquat flower and water are mixed, extracted and vacuum concentrated to obtain loquat flower extract.

The extraction device 1 comprises an extraction tank 11, a filter liner 12 (shown in fig. 2) arranged inside the extraction tank 11, and a lifting device 13. The filtering liner 12 is attached to the inner wall of the extraction tank 11, so that the volume of the filtering liner 12 is close to the volume of the extraction tank 11, the volume of the filtering liner 12 is large enough, and space waste is avoided.

As shown in fig. 2, 3 and 5, the filtering liner 12 has a double-layer structure, the outer layer is a rigid leak hole casing 121, the material can be 304 stainless steel, and the surface of the filtering liner is provided with leak holes 126 for the extracting solution to flow out. The inner layer is a filter screen inner layer 122, and the filter screen inner layer 122 is attached to and fixed on the inner wall of the leak hole casing 121. Fig. 5 schematically illustrates the distribution of a portion of the filter liner 12 from the outer layer to the inner layer. The upper part of fig. 5 is a rigid leak-off casing 121 as the outer layer and the lower part is a screen inner layer 122 as the inner layer. The pressure plate 123 presses the screen inner layer 122 against the rigid drain hole housing 121. The inner screen layer 122 may be in shape matching the rigid casing 121, for example, in this embodiment, the rigid casing 121 is cylindrical, and the inner screen layer 122 is cylindrical in shape matching the rigid casing 121. The inner screen layer 122 is soft, so the inner screen layer 122 can be coated on the inner wall of the rigid drain hole casing 121, and the inner screen layer 122 is fixed by the pressing plate 123. The inner screen layer 122 is of a soft material and has smaller openings, resembling a transparent gauze.

In the above embodiment, the inner layer 122 of the filter screen has a filtering function, so that the pore diameter is smaller than that of the rigid casing 121, the mixed liquid in the inner layer 122 of the filter screen is heated to obtain the extract, filtered out by the inner layer 122 of the filter screen, and flows to the portion between the filter liner 12 and the extraction tank 11 through the leak hole 126 on the casing 121 of the rigid leak hole. Specifically, referring to fig. 1 in combination with fig. 2, the lifting device 13 drives the filter liner 12 to lift up relative to the extraction tank 11, so that the filter liner 12 is separated from the extraction tank 11 up and down, and the extracting solution flowing out of the filter liner 12 falls into the extraction tank 11, and then the communication valve 41 is opened, so that the extracting solution flows into the vacuum concentration device 2. Meanwhile, the lifting device 13 can also drive the filtering liner 12 to descend and return to the interior of the extraction tank 11 to be embedded with the extraction tank 11. Referring to fig. 2, the peripheral wall of the filter inner container 12 may be provided with a plurality of handles 125, and the lifting device 13 lifts and lowers the filter inner container 12 by hooking the handles 125.

Referring to fig. 2, the filtering liner 12 of embodiment 1 has an upper cover 124 to prevent the extraction liquid from boiling and rolling during heating and overflowing from the filtering liner 12. In the above embodiments, the plant volume added to the filter liner 12 is less than one third of the volume of the filter liner 12, and more specifically, for example, the loquat flower is added in a volume less than or equal to one fifth of the volume of the filter liner. Also, the upper cover 124 is a double-layer structure, including a rigid perforated shell and an inner layer of a filter screen, which are the same as the cylindrical portion of the filter liner 12, and the upper cover 124 is used to cover the opening of the filter liner 12, so as to ensure that the plant particles do not leak out when the mixed solution rolls over, and at the same time, the liquid can either pass through the cylindrical portion of the filter liner 12 or flow through the holes in the upper cover 124. In this embodiment, the upper cover 124 is engaged with and fixed to the rigid casing 121.

Further, in the above-described embodiment, the leak holes on the rigid leak hole casing 121 and the upper cover 124 are uniformly distributed. More specifically, the plurality of leak holes are uniformly distributed on the peripheral wall, the bottom wall and the top surface of the upper cover of the filter liner 12. Thereby increasing the fluidity of the liquid and exerting a similar effect to stirring. In the extraction, the heating temperature is 180 ℃, the extracting solution is boiled and rolled, the liquid shuttles in the leak holes to increase the disturbance of the liquid, the extraction of the effective components in the plants is more facilitated, and the leakage of the plant slag can be avoided. Referring to fig. 1, during the boiling extraction, the evaporated steam is returned to the extraction tank 11 through the condenser 14 provided on the extraction device 1.

Experiments show that in the embodiment, the holes are uniformly distributed and have the diameter in the range of 4-6 mm, so that the liquid circulation effect is better, a special stirrer is not required to be arranged in the filtering liner 12, and the mixing and extraction of the liquid and plants can be realized more efficiently. Preferably, the weep hole diameter is 5mm. Furthermore, the mesh size of the inner layer of the filter screen is 500-800 meshes, so that the filtering with plants can be better realized, and the purity of the extracting solution is ensured. Specifically, the mesh size of the inner layer of the filter screen of the embodiment is 500 meshes, and meanwhile, the equipment cost control and filtering requirements are met.

In the above embodiments, a filter is provided on the path communicating with the vacuum concentration device 2 from the extraction tank 1, thereby further ensuring that the obtained extract is pure and free from impurities. It was found by examination that, referring to fig. 1, the paste obtained by the filtration through the filter 42 and the concentration was smooth, light was transmitted without any particulate feeling, and the quality of the finished product was high. Further, with continued reference to fig. 1, the number of filters 42 in this embodiment may be two, for example, two filters may be connected in parallel, and only one filter may be used to perform filtration when in use, so that once one filter cannot be used, the other filter may be replaced in time without affecting the production.

In the above embodiments, referring to fig. 1, the vacuum concentration apparatus 2 includes a concentration tank 21, a condensation tank 22, and a vacuum suction assembly 3. The vacuum suction group 3 is used for sucking the concentration tank 21 into a negative pressure state, and the condensation tank 22 is positioned on a path where the concentration tank 21 is communicated with the vacuum suction assembly 3, and is used for collecting condensate evaporated and condensed from the concentration tank 21. I.e. the condensation tank 22 communicates with the condensation tank 21 and the vacuum pumping assembly 3, respectively, such that the vapor drawn from the condensation tank 21 condenses into a liquid which is collected in the condensation tank 22. The vacuum pumping assembly 3 comprises a vacuum pump 31 and a buffer tank 32, wherein the buffer tank 32 is positioned on a path communicated with the vacuum pump 31 from the condensing tank 22, and the buffer tank 32 is respectively connected with the condensing tank 22 and the vacuum pump 31, so that liquid can be temporarily stored in the buffer tank 32 if the liquid is pumped out from the condensing tank 22 during vacuum pumping, and damage to the vacuum pump 31 is avoided. As can be seen from fig. 1, the extraction tank 11, the filter 42, the concentration tank 21, the condensation tank 22, the buffer tank 32, and the vacuum pump 31 are sequentially connected in series, and the communication and closure of the serial channels are controlled by the valves provided in the serial paths.

With continued reference to fig. 1, one or more condensers are provided in the path from the condensing tank 21 to the condensing tank 22 for cooling the vacuum evaporated steam into condensed water. For example, the condenser 23 and the condenser 24 may be separately provided, and cooling may be performed by passing cooling water therethrough.

Further, the bottom of the concentrating tank 21 is provided with an outflow pipe 25, and after concentrating, the formed paste can flow into the storage tank through the outflow pipe 25. In the concentration process, other raw materials are added into the concentration tank 21, for example, rock sugar is added into the concentration tank 21 in the preparation of loquat flower extract, the rock sugar is in a blocky solid, the rock sugar is sunk to the bottom in the initial stage of being added into the concentration tank 21 through the feed inlet 211, and then is melted at the bottom and enters into a part of the outflow pipeline 25 through heating, after concentration is finished, sugar in the outflow pipeline 25 is solidified and remains, on one hand, at least a part of sugar in the mixed paste is not fully dissolved, and on the other hand, the pipeline is blocked by solid sugar so as to be unfavorable for the outflow of the subsequent paste. For this purpose, the utility model sets up the recoil valve 26 on the outflow conduit 25, the recoil valve 26 is closed, the outflow conduit 25 is closed, the concentration tank 21 is not communicated with outside; the recoil valve 26 is opened and the concentration tank 21 is communicated with the outside atmosphere.

Referring to fig. 1, a backflushing valve 26 is provided, and in combination with the negative pressure state of the concentration tank 21 itself, only a short time is required to open the backflushing valve 26 to communicate the bottom of the concentration tank 21 with the outside atmosphere, air can enter an outflow pipe 25 between the backflushing valve 26 and the concentration tank 21 through the backflushing valve 26 and backflush the outflow pipe 25, so that sugar deposited in the outflow pipe 25 can be flushed into the concentration tank 21 by the air flow to be mixed with the extract. The timing of the opening can be observed through the observation window 212 in the thickening tank 21, and the ice confection is seen to sink to the bottom, and the recoil valve 26 is opened when it has been melt deposited on the bottom. According to practice it has been found that the heating temperature during concentration is between 160 and 200 degrees and the backflushing valve 26 may be opened between 10 and 15 minutes of crystal sugar addition, at which time some of the crystal sugar has melted into the outflow conduit 25 between the backflushing valve 26 and the concentrating tank 21. The opening time is a few seconds, for example, 5 to 10 seconds. May be opened multiple times to ensure that the sugar in the outflow conduit 25 is totally backflushed back into the thickening tank 21. The dissolution of the sugar at the bottom can be checked through the viewing window 212 to see if the sugar still is deposited at the bottom to ensure complete backflushing.

In the production equipment of the utility model, due to the limitation of volume and structure, a section of outflow pipeline 25 is necessarily arranged between the backflushing valve 26 and the bottom of the concentration tank 21, so that the pipeline is prevented from being blocked by rock sugar by opening the backflushing valve 26. The backflushing valve 26 is not required to be connected with a device with backflushing effect, and the backflushing effect can be realized by only opening the backflushing valve 26 to be communicated with the outside atmosphere due to the negative pressure state of the concentration tank 21. In other embodiments, referring to fig. 1, a transfer pump 27 may also be provided, the transfer pump 27 being connected to the backflushing valve 26 for transferring liquid material from the concentrating tank 21, for example, when the concentration is completed, the transfer pump 27 is turned on to transfer the completed plant concentrate paste to a storage tank for storage.

As shown in fig. 1, in the above embodiments, the production apparatus further includes the heating assembly 6, and the heating assembly 6 includes the hot oil tank 61 and the oil delivery member 62. The hot oil tank 61 is used for heating oil, and the oil delivery member 62 is used for delivering oil to the extraction device 1 and the vacuum concentration device 2 and back to the hot oil tank 61 to heat the extraction tank 11 and the concentration tank 21. By arranging the heating means of the hot oil, the heating of the extraction device 1 and the vacuum concentration device 2 can be completed by arranging a set of heating components 6. In this embodiment, the extraction device 1 and the vacuum concentration device 2 are preferably set at the same heating temperature, so that the operation steps are simplified, and only the hot oil is required to be driven to circularly flow during heating. Through multiparty debugging, the heating temperature is 160-200 degrees. Too high a temperature can cause the mixing solution to tumble in the extraction tank 11 to be severe, and too low a temperature is unfavorable for extraction of the active ingredients, in addition, if crystal sugar remains in the bottom pipeline (such as the outflow pipeline 25 shown in fig. 1) of the concentration tank 21, maintaining a proper temperature can also ensure that crystal sugar remaining in the bottom pipeline remains liquid during concentration, which is favorable for subsequent backflushing procedures. Preferably, the heating temperature is the best for extraction and concentration at 180 degrees after multiple tests.

Further, the squeezer 5 further comprises a non-woven bag (not shown) for taking out the plant residues from the extracting tank 1, wrapping the plant residues in the non-woven bag, and putting the plant residues into the leakage cylinder 52, so that the gland 54 can be used for extruding more extracting solution, and the plant residues can be effectively prevented from flowing into the extruded extracting solution.
